Comment It was a BlackHat / DEFCON publicity stunt (Score 2) 26 26

Hackaday is pretty much spot on: http://hackaday.com/2015/07/14...

There's always posturing for PR before BlackHat and DEFCON. This was to get the researcher's name on people's radar.

Many a competent unix sysadmin could come up with something similar.

What's hilarious is that despite how easy it would be to make something like this, the "researcher" just bought a yagi antenna and posed for a picture. They didn't even bother to point the yagi antenna towards the ground, for that matter.

Comment Physics called... (Score 2) 549 549

It's preferable for the car that is struck to not release its brakes. Basic physics. The more the struck car moves, the more injuries from the passengers in it. Also, the struck car moves and hits another car, etc.

The struck car's momentum is what mitigates the impact for its occupants. Ideal would be deploying a system to keep the struck car from moving at all. Mercedes has a braking system they've been testing that would probably do the job. It's basically an airbag on the bottom of the car, with a very high friction surface.

Comment Europe has also had wire transfers (Score 4, Interesting) 294 294

Wire transfers are extremely common in Europe; virtually instantaneous, cheap, etc. Customers can do them themselves, person to person.

Here in the US? Anywhere from a day to WEEKS for absolutely no legitimate reason. You generally need a teller or branch manager to do it. At least $5; $40 if the transaction ends up going through the Fed.

It's 2015. Why does transferring money in the US take more than a minute and a few cents?

Comment actual stats: 35k trips, 80k miles a day (Score 3, Informative) 100 100

Most Citi bikes go ununsed as far as I can tell.

You tell wrong. There are 6,000 bikes in the system and there's roughly 35,000 daily users.

I personally would've rather seen cleaner, faster, quieter and more reliable subways than more advert-bikes. But it's not so sexy for citibank to donate a tiny fraction of the MTA's budget for some billboards/posters.

Thank goodness we have urban transit planners, people with degrees in this stuff. They are heavily, heavily pushing bicycle transit and bike shares. Not because it's 'sexy', but because it works.

You can plop down a bike share station in a matter of days or weeks (the biggest hassle are the community meetings) which affords enormous flexibility; it takes months to redo a bus route, and decades to plan a subway line. Bike share bikes convert a fair number of people over to bike ownership, too - and the presence or more bike riders on the city's streets makes the streets safer for everyone.

Comment Re:Don't give money to your alma mater. (Score -1, Troll) 348 348

Not only am I well aware of how an endowment is operated -- this is a regular topic of faculty meetings, for god's sake

Then don't say ignorant things like this:

"A bit of data: Harvard's endowment amounts to $1.7 million per student. With a reasonable return on endowment investment, hey could quite literally abolish tuition forever if they wanted to"

You could also demonstrate some basic knowledge on the subject by showing that you understand "Harvard University" isn't "undergraduate" - that's Harvard COLLEGE. Here you go again:

A 3.5% return on Harvard's 1.7 million per student endowment would give an annual income of $60,000, which is equal to Harvard's tuition plus room and board.

Why do you think room and board at Harvard College is $60K?

What do you think will happen when you direct all the investment income into student tuition and board?

Well? Here's a big hint (oooo, am I being "condescending" again?): paying everyone's tuition via the investment income doesn't change REVENUE. So what pays for all the things the endowment income WAS paying for, but isn't anymore?

Huh?

Well, Mr. Fucking I Teach Physics? Ever heard the expression "rob Peter to pay Paul"?

A bit of data: Harvard's endowment amounts to $1.7 million per student. With a reasonable return on endowment investment, hey could quite literally abolish tuition forever if they wanted to.

"Full disclosure: I'm a professor at a liberal arts college whose endowment per student is mediocre at best.

Clearly not a professor of finance, math, etc. given you don't understand that investment income on the endowment is what the school uses to help with operating and capital expenses. You avoid at all costs spending the endowment; you spend some of the investment income. Or, to put it in simpler terms a "liberal arts professor" might understand: selling the cow instead of the milk has enormous long-term impact.

Also, given Harvard is older than the United States (in fact, older than the Commonwealth of Massachusetts) - "forever" is a really strong word.

Harvard has a huge number of full-boat scholarships and when the endowment tanked, none of the schools dropped their scholarship levels. Several raised them.

Comment Re:is there a simple android edit/add client? (Score 1) 25 25

So there's eight or ten clients for android that support some sort of editing, which is precisely why I asked. Which of them actually has a usable interface for simply and quickly adding POI's?

I'm not going to go through the trouble of installing almost a dozen clients just to answer this question.

Comment is there a simple android edit/add client? (Score 3, Insightful) 25 25

On a slightly related note: I wanted to add minor resources like bike repair stations and water fountains in my city, and figured there MUST be an android app that would make this about as simple as "hold your phone over it for a bit to get an averaged position, now click this and then "water fountain".

Nothing that I could see was remotely this simple? Even the web editor is a nightmare of trying to figure out exactly how to do things...and the wiki didn't help much, either, with poor documentation on the various properties one can assign to an object.

Eh, not really. I guarantee you they have a lot of "real" security personnel.

This is about taking over control of the story; it's a sort of "pay no attention to the thing we don't want you to hear about" (ie the fact that their onboard infotainment/networking and satellite uplink systems are ludicrously insecure) and "pay attention to this other thing."

Now when you search for "united hacking", you'll get a billion stories about the bug bounty, and few about the original problem - that a passenger was able to walk all over stuff he shouldn't have been able to. It's already starting to work, a few hours in:

It also helps them look, to shareholders/the market/the public, like they're "responding" and making an effort to "improve security."

Comment After my Transformer Infinity, never again (Score 1) 48 48

After the incredible piece of shit that my TF700T was, never will I buy an Asus tablet again.

Nice screen (it was one of the first android tablets to have a really high-res screen), the graphics processor and CPU are fast...but they completely screwed the pooch on the flash architecture, making the thing crippled; any sort of disk IO causes it to slow to a crawl. There are all sorts of hacks to make just web browsing bearable, by using a ram disk to completely avoid the flash. People also put in the fastest SD cards they can find.

Didn't the Nexus 7, which they OEM'd, have similar issues?

Ford Explorer roof pillars were initially spec'd with a fairly high-grade steel. Citing costs, management refused to use the high-grade steel and instead used a weaker steel.

Result? Lots of roof-cave-ins on a vehicle that was prone to roll over.

Cloudfare blocks Tor exit nodes heavily; you have to fill out a captcha almost every other page refresh. It makes it almost impossible to navigate a website.

That seems incompatible with your distaste for "kowtowing to the enemies of freedom" and trying to allow customers access to your books even if a government doesn't want them to have access.

Gatekeeper also isn't "all MacOS X security". There's separate malware detection, and in order to do much of anything the user has to enter their computer account password.

It's a minor part of OS X security, mostly designed to keep casual users from installing stuff outside the apple store.
